MACHINE FOR GUIDING THE EDGES OF TEXTILE WEBS.

SPECIFICATION forming part of Letters Patent No. 487,352, datedDecember 6, 1892.

Application tiled May 16, 1890. Renewed May 12, 1892. Serial No. 432.725. (Model.)

To a/ZZ whom t may concern:

Be it known that I, JOSEPH J. ScHoLEIELD, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improvement in Machines for Guiding the Edges of Textile Webs, of which the following is a specification.

My invention consists in the improved construction and arrangement of the reversing devices which actuate the guide-roller or the guide-roller support to cause the proper lateral movement of the edge of the web toward the true guiding-line upon any specilic variation therefrom.

It also consists in the improved driving means for actuating the reversing devices.

Figure 1 represents a plan view of the machine. Fig. 2 represents an elevation of the same. Fig. 3 represents a section taken in the lineof Fig. 1. Fig. 4. represents a seotion taken in the line y y of Fig. l. Fig. 5 represents a section taken in the line ,e z of Fig. l. Fig. 6 represents a detail section taken in the line m of Fig. 3. Fig. 6a represents a section of the engaging members, taken in the line y y of Fig. 3, showing the opposite inclination of the ribs which engage with the screw. Fig. 7 represents a modification in which the machine is driven by the web. Fig. 8 represents the attachment of my improvement to a cloth-drying machine, the guiding movement of the rollers being effected by the forward movement of the web.

In the accompanying drawings, Figs. 1 and 2, A represents the frame of the machine, and B the main shaft, having upon its outer end a pulley C, as heretofore. U pon the shaft B is placed the loosely-sliding sleeve D, held to rotate With the shaft by means of the pin a, which projects from the shaft B into the groove b, made in the cavity of the sleeve. (See Fig. 5.) The sleeve D is provided exteriorly for about one half of its length with the oppositely-inclined right and left hand spiral grooves c o', which cross each other at opposite sides of the sleeve, thus forming by means of the intervening projections or ribs b2 a combined right and left hand screw, and at the opposite half with the equidistant annular grooves d d d, which, with the intervening annular portions e e, form a circular rack adapted to engage with the teeth of the gear E. The sleeve D is prevented from sliding too easily upon the shaft B by means of the pressure-springf, which bears upon the top of the annular portions e..

Upon the bed of the frame A are placed the vibratory engaging members F F', which are held in proper position by means of the guidebearings g g and the upright guide-pins h h,

the engaging member F being provided with G G', respectively, and are operated in the opposite direction to be thrown out of engagement With the said grooves by means of the.

cam I-I upon the shaft I, the said cam H' engaging with the projections a3, which lextend upward from the engaging members, and the said shaft being driven from the shaft B by means of the gear fupon the shaft B and the gearj upon the shaft I and the intermediate gears 7n and Z, which are attached to each other and revolve with the shaft m. The guidetable J is supported from the bed of the frame A by means of the arm n, and is provided with the parallel slots o o, which are adapted to receive the arms `,fp of the detector K, the said detector being pivoted to the standard L by means of the screw q, the lower end r of the detector being adapted to move back and forth in front of the ends s of the engaging members F F. The gear E or a suitable segment is attached to a supporting-spindle z, held in the frame A, as shown in section in Fig. 5, the said gear being provided at one side with a head M, which serves to support the horizontal guiding-pins t t, and also the intermediate stud u, upon which is loosely placed the guide-roller N, the said guide-roller' being preferably set with spurs, as in the rollers of loom-temples, and the proper angular movement of the axis of the guide-roller will be effected by the sliding movement of the sleeve D, which is in engagement With the teeth of the gear E, the sliding move- IOO ment of the said sleeve D being subjected to the resisting frictional action of the pressurespringf, so that the guide-roller will be frictionally held in its set position when the engaging members F F are out of engagement with the projections b2 of the sleeve D.

Tothe upper end of the standard P is attached the rod tu, upon which is placed the sliding or direct-actingguide-roller N, which is operated back and forth upon the rod w by means of the arm x, which extends from the pivoted head M and enters the annular groove y of the roller, so that whenever the direction of the guide-roller N is changed by the angular movement of the supporting-spindle e in either direction a corresponding movement in a direct line willbe imparted to the guide-roller N to cause a quick movement of the web to the true line from the point of variation. When the edge e of the web Q is being drawn over the guide-table J in the proper line, as shown by the full line in Fig. 4 and by the dotted line v r) in Fig. l, then the end r of the detector will serve to prevent either of the engaging members F F fromengagement with the spiral grooves of the sleeve; but when moved either to the right or to the left by the action ofthe edge t; of the web Q upon the armspp of the detector, which detector is overbalanced, so that the said arms will fall toward the table, then one ot' the said engaging members will pass into engagement with the spiral grooves of the sleeve to cause the movement of the same in one direction until the said member is thrown out of engagement by the partial rotation of the cam H, and upon the continued rotation of the said cam the said member will be released and again pass forward into engagement with the groove of the sleeve, thus causing another movement of the sleeve in the same direction as that of the former movement, and the operation will continue until the resulting angular movement of the guide-roller N and direct movement of the guide-roller N has caused the return of the edge of the web to the proper guide-line, and then the said engaging member will be prevented from passing into engagement with the sleeve by the action of the end r of the detector, as before, and when the variation in the position of the edge of the web from the proper line is in the opposite direction, so that the opposite engaging member will be released from engagement with the endfr of the detector, then the sleeve D and guide-rollers N N will be moved in the reverse direction to again return the edge of the web to the proper line.

A moditication of my invention is shown in Fig. 7,in which the screw projections or ribs b2 of the sleeve are formed by the crossgrooves c c', of greater pitch than shown in Figs. l, and by reason of the comparativelyslight angular movement of the axis of the guide-roller N required to guide the edge of the web the connection between the sleeve D and the guide-roller support may be made by means of a single groove d of the circular rack, the said groove being adapted to receive a stud t', which projects downward from the arm u', attached to the guide-roller support and extending above the sleeve, the said stud being equivalent to a single tooth of the gear E, which enters a single groove of the rack, and upon the movement of the sleeve in either direction the proper angular movement will be imparted to the said guide-roller.

The application of my improved guiding mechanism for guiding the web to the cylinders of a cloth-drying machine is shown in Fig. 8, in which P4 represents the initial cylinder of the series, and B the driving-roller, over.

which the web Q from the batch-roll R is made to pass on its passage to the cylinder P4, so that the forward movement of the web will serve to revolve the shaft B and the sliding sleeve D, and in carrying out this application of my invention the described automatic guiding devices are duplicated,'one set of devices being located at each side of the machine, as shown in the drawings; but in some cases a single guiding device located at one side may be employed.

lt is to be understood that in the application of my invention for the purpose of guiding webs of cloth to cloth-finishing machines through the action of a driving-roller which' is operated by the web I do not limit myself to the special construction of the reversing mechanism.

I claim as my invention- .1. The combination, with a rotating shaft and a sliding sleeve made to rotate with the shaft, of a movable guide-roller operatively connected with the rotating and sliding sleeve, whereby upon the sliding movement of the sleeve in either direction upon the shaft a guiding movement will be imparted to the guide-roller, substantially as described.

2. The combination, with the rotating shaft and a sliding sleeve made to rotate with the shaft and provided with the right and leftv `hand spiral grooves, of the engaging members which are adapted to cause the movement of the sleeve in opposite directions, means for actuating the engaging members, and a detector for limiting the movement of the engaging members as required, substantially as described.

3. The combination, with the rotating shaft and a sliding sleeve made to rotate with the shaft and provided with the right and left hand spiral grooves, of the engaging members which are adapted to cause the movement of the sleeve in opposite directions, means for actuating the engaging members, the detector for limit-ing the movement of the engaging members as required, and a guide-roller having its axis adapted for angular movement and operatively connected with the sleeve, subtantially as described.

4. The combination, with the slotted table and the pivoted detector adapted to enter the IIO slot in the table and bear upon the edge of the fabric, of the engaging members adapted to engage with the opposite end of the detector and means for operating the engaging members, substantially as described.

5. The combination, with the means for drawing the web forward through the machine, a shaft rotated by the forward movement of the web, and a sliding sleeve made to rotate with the shaft, of a guide-roller having its axis adapted for angular movement and operatively connected with the rotating sliding sleeve to impart a guiding movement to the edge of the web, substantially as described.

6. The combination, with the detector, the engaging members, the operating cam and springs, and the sliding sleeve provided with the right and left hand spiral grooves, which together constitute a reversing mechanism, of a pivoted guide-roller in operative connection with the reversing mechanism, a direct-acting guide-roller in operative connection with the reversing mechanism, and the drivingroller which is actuated by the forwardlydrawn web to produce the required regulating movement of the guide-roller, substantially as described.

7. The combination, With the detector, the engaging members, the operating cam and springs, and the sliding sleeve provided with Aright and left hand spiral grooves, which together constitute a reversing mechanism, of a guide-roller and guide-roller support adapted for angular movement and operatively connected with the reversing mechanism and the driving-roller which is actuated by the forwardly-drawn Web to produce the required regulating movement of the guide-roller, substantially as described.

8. The combination, with the detector, the engaging members, the operating cam and springs, and the sliding sleeve provided with the right and left hand spiral grooves, which together constitute a reversing mechanism, of a guide-roller and guide-roller support adapted for angular movement, and a directacting guide-roller, both of said guide-rollers being operatively connected with the reversing mechanism, and the driving-roller, which is actuated by the forwardly-drawn web to produce the required regulating movement of both guide-rollers, substantially as described.

9. The combination, with a cloth-finishing machine, of duplicate automatic guiding devices, one set of said devices being located at each side of the machine, and a driving-roller which is actuated by contact With the forwardly-drawn web for connectedly driving said guiding devices.

10. The combination, with an automatic guiding device, of a stationarily-supported driving-roller adapted for engagement with the forwardly-drawn Web to operate the said guiding device.

1l. A cloth-guiding machine automatically actuated and controlled by the fabric passing through it, consisting, substantially, of a guide-roller, a roller-support adapted for angular movement, the engaging members, the cam and springs for operating the engaging members, the frictionally resisted sliding sleeve having the right and left hand spiral grooves to receive the engaging members and in operative connection With the roller-support, the cloth-driven roller for rotating the cam and the sleeve, and the detector for limiting the movement of the engaging members to eect the proper regulating action of the guide-roller upon the running edge of the web.
